# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Direct final rule.

# SUMMARY:

EPA is taking direct final action approving State Implementation Plan (SIP) revisions submitted by the State of Utah on November 11 and November 23, 2005. The revisions are to the Utah Administrative Code (UAC) rule R307-101-2 and (1) incorporate by reference the federal definition of “Volatile Organic Compounds” (VOC), and (2) update the definition of “Clearing Index”. The intended effect of this action is to make federally enforceable these revised definitions to the Utah SIP. This action is being taken under section 110 of the Clean Air Act. 

# DATES:

                        This rule is effective on November 21, 2006 without further notice, unless EPA receives adverse comment by October 23, 2006. If adverse comment is received, EPA will publish a timely withdrawal of the direct final rule in the                         **Federal Register**                         informing the public that the rule will not take effect.

## I. General Information 

### A. What Should I Consider as I Prepare My Comments for EPA? 

                    1.                     *Submitting CBI.*                     Do not submit this information to EPA through                     *http://regulations.gov*                     or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.                 

                    2.                     *Tips for Preparing Your Comments.*                     When submitting comments, remember to:                 

                    a. Identify the rulemaking by docket number and other identifying information (subject heading,                     **Federal Register**                     date and page number).                 

b. Follow directions—The agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number. 

c. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes. 

d. Describe any assumptions and provide any technical information and/or data that you used. 

e. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced. 

f. Provide specific examples to illustrate your concerns, and suggest alternatives. 

g. Explain your views as clearly as possible, avoiding the use of profanity or personal threats. 

h. Make sure to submit your comments by the comment period deadline identified. 

## II. What is the Purpose of This Action? 

EPA is approving revisions to the definitions of Volatile Organic Compounds (VOC) and Clearing Index in Utah's rule R307-101-2. On November 11, 2005, the State of Utah submitted revisions to the definition of VOC. The revised VOC definition incorporates by reference 40 CFR 51.100(s). On November 23, 2005, the State of Utah submitted a revised definition of the Clearing Index. The revised definition of the Clearing Index reflects a more specific and expanded clearing index forecast generated by the National Weather Service (NWS). 

## III. What is the State Process to Submit These Materials to EPA? 

Section 110(k) of the CAA addresses our actions on submissions of revisions to a SIP. The CAA requires States to observe certain procedural requirements in developing SIP revisions for submittal to us. Section 110(a)(2) of the CAA requires that each SIP revision be adopted after reasonable notice and public hearing. This must occur prior to the revision being submitted by a State to us. 

The Utah Air Quality Board (UAQB) held a public hearing for the revised definition of VOC on May 24, 2005. The definition was adopted by the UAQB on July 6, 2005 and became State effective on July 7, 2005. The UAQB held a public hearing for the revised definition of Clearing Index on July 19, 2005. The definition was adopted by the UAQB on September 7, 2005 and became State effective on September 8, 2005. The Governor submitted these SIP revisions to us on November 11 and November 23, 2005 respectively. 

We have evaluated the Governor's submittal of these SIP revisions and have determined that the State met the requirements for reasonable notice and public hearing under section 110(a)(2) of the CAA. As required by section 110(k)(1)(B) of the CAA, we reviewed these SIP materials for conformance with the completeness criteria in 40 CFR 51, Appendix V and determined that the submittals were administratively and technically complete. 

## IV. EPA's Review of the State of Utah's November 11 and November 25, 2005 Submittals 

### 1. Changes to the Definition of Volatile Organic Compounds 

Utah's revision to the definition of VOC in Rule R307-101-2 incorporates by reference federal regulation 40 CFR 51.100(s)(1) as updated by EPA on November 29, 2004 (69 FR 69290). This revision to the Utah SIP is, therefore, approvable. 

### 2. Changes to the Definition of the Clearing Index 

Utah's revised definition of the Clearing Index in Rule R307-101-2 reflects technological advances implemented by the National Weather Service (NWS). The value of the clearing index forecast provided by NWS is used to foresee the degree to which an area's air quality would be degraded by open burning operations or by industrial processes. In the 1970s the NWS began forecasting a daily clearing index for three air basins in the State of Utah. New technology, implemented in recent years, has allowed the NWS to upgrade its clearing index forecast to a three-day forecast for any point in the State instead of the previous three air basins. The NWS clearing index forecast is accessible online at no cost, through an interface on the NWS Web site. Based on the above, we have concluded the revised definition of the Clearing Index is approvable. 

## V. Final Action 

EPA is approving, through direct final rulemaking, revisions to the definitions of VOC and of the Clearing Index in Utah's rule R307-101-2. 

                    Section 110(l) of the CAA states that a SIP revision cannot be approved if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress towards attainment of a                           ( print page 55286)                        NAAQS or any other applicable requirement of the CAA. The revised definitions of VOCs and of the Clearing Index will not interfere with attainment, reasonable further progress, or any other applicable requirement of the CAA.                 

                    EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comments. However, in the “Proposed Rules” section of today's                     **Federal Register**                     publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision if adverse comments are filed. This rule will be effective November 21, 2006 without further notice unless the Agency receives adverse comments by October 23, 2006. If the EPA receives adverse comments, EPA will publish a timely withdrawal in the                     **Federal Register**                     informing the public that the rule will not take effect. EPA will address all public comments in a subsequent final rule based on the proposed rule. The EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.                 

## VI. Statutory and Executive Order Review 

                    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601*et seq.*). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 104-4).                 

This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant. 

                    In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501*et seq.*).                 

                    The Congressional Review Act, 5 U.S.C. 801*et seq.*, as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the                     **Federal Register**                    . A major rule cannot take effect until 60 days after it is published in the                     **Federal Register**                    . This action is not a “major rule” as defined by 5 U.S.C. 804(2). Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by November 21, 2006. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
